I used it about 4 or 5 times, replacing the gas and toner. Easy-to-use carbonated spray mist for carbonated beauty treatments. It was working until recently, so I think the main unit is still usable. You can use it if you purchase gas and toner from the official online store. Even if there is a problem after purchase, I think it can be repaired even if the warranty period has expired. The warranty has expired as it was purchased about 3 years ago, so it is not included. I am selling it at a low price, so why not give it a try? Returns and exchanges are not accepted after purchase. Also, please refrain from purchasing if you do not understand that this is a used item or if you are a very sensitive person. It will be sent in the condition shown in the fifth photo. The toner and gas are empty and are not included. ReFa Mist PLOSION Mist MEGLY Mist
